Read the following passage about nocturnal animals.
Nocturnality is an animal behaviour characterised by activity during the night and sleep during the day. The common adjective is "nocturnal", versus its opposite “diurnal”.
Nocturnal creatures generally have highly developed senses of hearing and smell, and specially adapted eyesight. Such traits can help animals such as the Helicoverpa zea moth to avoid predators. Some animals, such as cats and ferrets, have eyes that can adapt to both low-level and bright day levels of illumination. Others, such as bushbabies and some bats, can function only at night. Many nocturnal creatures, including most owls, have large eyes in comparison with their body size to compensate for the lower light levels at night.
Being active at night is a form of niche differentiation, where a species' niche is partitioned not by the amount of resources but by time (i.e. temporal division of the ecological niche). For example, hawks and owls can hunt the same field or meadow for the same rodents without conflict because hawks are diurnal and owls are nocturnal.
